[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。  e]$s t?  
3o/[t  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： +LJ73 !  
enableservice('AutomationServer', true) @>7%qS  
enableservice('AutomationServer') Y}KNKO;  
MiX43Pk]  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 iH'p>s5L

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： 9:lFo=  
1. 在FRED脚本编辑界面找到参考. +aAc9'k  
2. 找到Matlab Automation Server Type Library a$fnh3j[  
3. 将名字改为MLAPP /B

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 -$g#I

1. 创建Matlab服务器。 ,`sv1xwd  
2. 移动探测面对于前一聚焦面的位置。 ?\n> AC  
3. 在探测面追迹光线 3$ PV2"  
4. 在探测面计算照度 HK%7g  
5. 使用PutWorkspaceData发送照度数据到Matlab 43 :X,\~)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 !dT4  
7. 用Matlab画出照度数据 l}P=/#</T  
8. 在Matlab计算照度平均值 _tycgq#  
9. 返回数据到FRED中 Rk8P ax/JK
